Cover window, display device comprising the same and manufacturing method thereof

Abstract

A cover window according to an embodiment includes a base layer, and a first sub-opaque layer disposed on the base layer, and the first sub-opaque layer includes additives having magnetic properties.

What is claimed is: 
     
         1 . A cover window, comprising:
 a base layer; and   a sub-opaque layer disposed on the base layer; and   the sub-opaque layer includes a plurality of additives having magnetic properties.   
     
     
         2 . The cover window of  claim 1 , wherein the plurality of additives include at least one of Fe, Al, FeO, and Fe 2 O 3 . 
     
     
         3 . The cover window of  claim 1 , wherein the plurality of additives have a core-shell structure. 
     
     
         4 . The cover window of  claim 3 , wherein
 the core-shell structure includes a core including at least one of SiO 2  and BaSO 4 , and   the core-shell structure includes a shell including aluminum.   
     
     
         5 . The cover window of  claim 1 , wherein the plurality of additives are included in the sub-opaque layer in an amount in a range of about 5 wt % to about 15 wt %. 
     
     
         6 . The cover window of  claim 1 , wherein the plurality of additives are disposed adjacent to a surface of the sub-opaque layer. 
     
     
         7 . The cover window of  claim 1 , wherein a surface of the sub-opaque layer has a roughness in a range of about 0.4 micrometers to about 0.7 micrometers. 
     
     
         8 . A display device, comprising:
 a display layer disposed on a substrate; and   a cover window disposed on the display layer, wherein   the cover window comprises:
 a base layer; and 
 a first sub-opaque layer disposed on the base layer, and 
   the first sub-opaque layer includes a plurality of additives having magnetic properties.   
     
     
         9 . The display device of  claim 8 , wherein the plurality of additives include at least one of Fe, Al, FeO, and Fe 2 O 3 . 
     
     
         10 . The display device of  claim 8 , wherein the plurality of additives have a core-shell structure. 
     
     
         11 . The display device of  claim 10 , wherein
 the core-shell structure includes a core including at least one of SiO 2  and BaSO 4 , and   the core-shell structure includes a shell including aluminum.   
     
     
         12 . The display device of  claim 8 , wherein the plurality of additives are included in the first sub-opaque layer in an amount in a range of about 5 wt % to about 15 wt %. 
     
     
         13 . The display device of  claim 8 , wherein the plurality of additives are disposed adjacent to a surface of the first sub-opaque layer. 
     
     
         14 . The display device of  claim 13 , wherein the surface of the first sub-opaque layer has a roughness in a range of about 0.4 micrometers to about 0.7 micrometers. 
     
     
         15 . The display device of  claim 14 , further comprising:
 an adhesive layer disposed between the display layer and the cover window.   
     
     
         16 . The display device of  claim 15 , wherein the surface of the first sub-opaque layer faces the adhesive layer. 
     
     
         17 . The display device of  claim 8 , wherein the cover window further includes a second sub-opaque layer disposed between the first sub-opaque layer and the base layer. 
     
     
         18 . A method of manufacturing a cover window, comprising:
 preparing a base layer;   applying a material layer containing an additive on the base layer;   applying a magnetic force on the material layer; and   curing the material layer to provide a sub-opaque layer.   
     
     
         19 . The method of manufacturing a cover window of  claim 18 , wherein the additive has magnetic properties. 
     
     
         20 . The method of manufacturing a cover window of  claim 18 , wherein the applying of the magnetic force, the additive moves adjacent to a surface of the material layer.
